sixDoF restraint 'tabulatedAxialAngularSpring' does not read tabulated files properly
I am struggling to use sixDoF restraint 'tabulatedAxialAngularSpring', which is to impose a constant resistant torque on turbine shaft to simulate the reaction from a generator geared to turbine.
Have tested .dat files in many ways, but still not successful. The error info is always 'error in IOstream "xxx.dat" for operation Istram::operator()'.
No examples can be found from official tutorials using 'tabulatedAxialAngularSpring', and no discussions can be found from internet.
However, I do believe 'tabulatedAxialAngularSpring' is a great option and should work properly in someway.
